• $3.20 each, there are samples available in the unpackaged die. See LM107 product folder.

 

 

 

 

 

 

 

  • The improved amplifier is LMC6081
    $0.52 for the LF411 and $1.10 for the LMC6081

 

 

 

 

 

 

  • Its common-mode range does not go to the POSITIVE rail, whereas the LM107 and LF411 have their CM range to the POSITIVE rail. The LMC6081 can also run on 15 volts (max) total supply, but not as high as the 30 volts of the LM107 or LF411.

    See datasheets LM107, LF411, and LMC6081

 

 

 

 

 

 

 

 

 

 

 

 

  • The LM107's input current is too big. The LM107 and LF411 common-mode range goes to the positive rail, whereas the LMC6081 has its CM range to the negative rail. The LMC6081 can run as low as 4.5 volts total supply, and the LF411 needs at least +/- 5 volts (10 volts total supply voltage).

  • A higher value of the compensation capacitor creates lower output noise, less slew rate, and better tolerance of capacitive loads. A smaller value of a compensation capacitor creates a larger bandwidth, more slew rate and less of a phase shift. See AN-20.
